Step-by-step explanation:
10. 12
11. 500
12.8
13.45
the coefficient is any real number so in 67xy the coefficient would be 67
You would do ten columns of ten and then you would just do the remaining.
Remember:
A triangle is always 180 degrees and so is a straight line so 360 degrees in total:
1) Add 92 and 123 which equals 215
Then 360 subtracted by 215 is 145
Answer: 145
2) add 100 and 25= 125
360-125= 235
Answer: 235 degrees
